To all whom, ama/y concern: V

Be it known that I, WILLEr C. WELLs, a citizen ofthe United States, anda resident of Tiffin, in the county of Seneca and State of Ohio, haveinvented certain new and useful uImprovements in Well-TubesforDrivc-Wells ;v and I do herebyA declare that the following is a full,clear, and exact description of the invention, which will enable othersskilled i-n the art to'which it appertains to make and use the same,reference being had to the accompanying drawings, which form a part ofthis specification, and in which- "Figurel is a side view, partly insection, of ,a well-tube and of my improved strainer andv tubulardrive-rod. Fig. 2 is a similar view of the lower end of the tube,showing the drive-l rod removed and a valve-seat and valve insertedinthe-rop of the strainer. Fig. 3-is-a-Y perspective view, with portionsbroken away, of the lower end of the drive-rod or deliverypipe and ofthe upper end of the strainer, showing it arranged for withdrawing thepartly screw-threaded sleeve at the upper end .of the strainer; andFigs. 4 and 5 are horizonvtal sectional views of the lower end of thedelivery-pipe or tubular drive-rod and of the partly-threaded sleeve atthe upper end of the strainer, showing them in their two differentpositions, the view being taken on line x w, Fig. l.

Similar letters of reference indicate corre spending parts in all thefigures. My invention has relation to well-tubing, and more especiallyto devices for seating strainers in sand, and at the same time pump* ingout the ne sand bythe same motion and tool that drive or seat thestrainer; and it consists to that end in the improved construction andcombination of parts of the same, as here inafter more fully describedand claimed.

In the accompanying drawings, the letterA indicates the well-tube, whichis vprovided at its lower end with a shoe, B, screwed or otherwisesecured to the tube, and provided with a tapering` bore decreasing indiameter toward `thelower end, as shown at C.

, Dis the strainer, which is provided with thep'sual drivepoint,E,extending a short disconcussion-block, F, against which thetubulardrive-rod or deliveryfpipe G may act, and the strainer is provided withperforated sides of any desired construction, and provided at its upperend withva tapering sleeve, H, having the vsame external taper as theinternal taper of the shoe, and provided' with an internal screw-thread,I, which extends above the upper edge of the strainer.

A sleeve, J, is secured with its reduced and screw-threaded lower end,K, in the upper threaded portion of the sleeve H, and has an internalscrew-thread, L, which is cut away at alternating points, so as to formsmoothecsections, the drawings showing the thread as being cnt away atalternating quarters ofthe inner surface of the sleeve, although thethread places. Y t v y The lower' end of the delivery-pipe or tubulardrive-rod G is screw-threaded, as shown lat N, and a sleeve, O, issecured upon that en'd, having an internal screw-thread, l?, at itsupper end, which fits upon the said end,'the sleeve forming a shoulderor valve-seat, Q, below the threaded portion, upon which valveseat anupwardly-opening valve, B, fits.y

The outside of the sleeve O is -provided with alternating smoothsectionsv S and screwcorresponding in width to the similar sections uponthe inside of sleeve J, so that the exter nelly-threaded sleeve 0 may bedrawn up through the internallythreaded sleeeve J when the ,threadedsections of one sleeveare placed opposite to the smooth sections of theother sleeve, while by turning the externallyl threaded sleeve so as tobring the threaded sections of both sleeves to engage each other neotedby their respective sleevesl so as to be raised or lowered together.

When lthe device is in operation, the material in which it is destinedto work .being sand, the delivery-pipe is reciprocated within its bottomat each blow, and at the same time pumpingup alliine sand which entersthrough tance up within the strainer, so as to form a the strainer, soas to leave the coarser partitions M of the same width as the threaded.

may betcntwaway inv any-desired numhereot-` 8o threaded sections T ofthe same width and the delivery-pipe and the strainer may beeonthestrainexy striking the concussion-block at roo v drawing the saidpipe may follow, and the strainer pipe is withdrawn from thepstrainer,

sleeve.)r and turned so as to engage the threaded cles of sand to fornia filter around the tube, l and by thus. reciprocating' thedelivery-pipe or drive-rod the strainer .and afterwardvthe tubeareforced down, the delivery-pipe acting as a sand-pump 'at the sainetime as it acts as a drive-rod. f

` When itis desired' to stop driving the strainer and tube farther down,the deliveryl which' may be doneby bringing thesrnoo'th portions of onesleeve-to register with the threaded portions of the other sleeve, andafter .witha number of the threads of the screwLthreaded sections of thesleeve O may be lled for a portion of their length,

when the pipe is again inserted with its "threaded sleeve into theinternallythreaded the filled portions or shoulders (shownat' U in Fig.3) bearing against the 'ends of the threaded sections of sleeve J, so asto allow the said sleeve to be nnser'ewed from the tapering sleeve andwithdrawn.

AV valve seat, V, having an upwardlyopening valve, W, is now screwedinto the internal thread of the tapering sleeve of the strainer, whichhas been forced down so as to form a tight joint at the tapering sleeveand the tapering bore of the shoe of the tube, and4 the well is readyfor use. f i

1f it is desired to withdraw the strainer fromy .thetnhe at anytinieduring' construction er afterward, the threaded :portionsof thedelivery-pipe and oi the internally-threaded sleeve of the strainermaybe engaged; when bydrawing the delivery pipe upward the strainer maylikewise be raised hy raising the well-tube.

Having thns described my invention, I claim anddesire to secure byLetters Fatent of the port-ions,

'for the purpose -upper end United States* 1. The combination, with. thewellv--tuoe having the shoe at its lower. end, having the tapering bore,of the strainer having thetapering sleeve secured at its upper end,corresponding in taper to the Ibore of the shoe, as

'and for the purpose 4shown and set forth.

2. The combination of the strainer having the sleeve at its upper end,formed with altermating threaded and smooth portions at its inner side,with the delivery-pi pe provided at its lower end with the sleeve havingalternating smooth and screw-threaded portions upon its outside,corresponding in width to each other, as and shown and set forth.

3. The combination of the strainer, having the drivepoint and theconcussion-blockv at its lower end, with the tubular drive-rod havingthe upwardly opening delivery valve within its lower end, as and for thepurpose 'shown and set forth.

4. In a well-tube, the combination of `the welltube, the strainer havingmeans for pre-4 venting it from slipping out of the lower end oftheWell-tube, and having the sleeve at its and screw-threaded 'portionsupon 'its inner lside, and the delivery-pipe having the sleeve' at itslower end provided lwith alternatingy smooth and screw-threaded portionsnpbnits vonter side,and formed with an internalvalve seat provided withan upwardly-'opening valve, as and for the purpose shown andset forth.-f i Y In testimony that I claim the foregoing as in. presence of twowitnesses. y
